From publisher blurb:
Taste of the Forbidden Fruit!
Do you wish that alchemy in your game had a little more “oomph?” Have you ever been disappointed that no matter what it is that you’re trying to craft, all it takes is gold, time, and a skill check, with no concern as to what ingredients you’re using or how they’re prepared? Have you ever GM’d for a player who always seemed to want to wander off into the woods (or the merchant district) in search of rare and exotic reagents and compounds for his next magical experiment, and struggled to come up with an exciting and suitably fantastic material for him to find?
Then this is the book for you. Successor to the critically-acclaimed A Necromancer’s Grimoire: The Secret of Herbs, Weekly Wonders: Fiendish Herbs is a stand-alone product that continues its predecessors' unique approach to the sorts of low-cost special substances that can be created with the Craft (alchemy) skill. Presented herein are five new fiend-themed herbs found on the lower planes, with very special properties, as well as everything you need to know about how to use them in your game.
Included are the abyssal maw, a demonic pitcher plant whose bile can corrupt or destroy nearly anything, the corruption vine, a plant that feeds on sin and can be used to detect evil and even inspire it in others, hellmoss, an infernal, psycho-reactive fungus that can grant a variety of benefits, but is highly addictive and always comes with a cost, reaper’s blossom, a flower associated with daemons which is as beautiful as it is deadly, and the soul tree, a plant that uses soul larvae as nourishment and contains the essence and memories of lost souls.
